英語作文 篇1
在英語作文教學(xué)中,對學(xué)生作文進(jìn)行批改一直被師生共識為提高寫作能力的有效手段。但是,考慮到時間、精力、作文收發(fā)等方面,又不得不承認(rèn)效率不高。在大規(guī)模語言考試中,作文又是必不可少的題型,閱卷工作量和閱卷的信度等問題一直以來都不能讓我們?nèi)缫狻a槍@一難題,電腦智能自動評分系統(tǒng)提供了可以信賴、值得期盼的解決方案。
在PEG、IEA、E-rater、冰果、MY Access、IntelliMetric等幾種智能評分系統(tǒng)中,本文選取IntelliMetric系統(tǒng)進(jìn)行研究,對其評價標(biāo)準(zhǔn)進(jìn)行理論分析,對其所評分的作文進(jìn)行跟蹤評析,發(fā)現(xiàn)其通過對學(xué)生作文按照若干評分標(biāo)準(zhǔn)問題進(jìn)行回應(yīng)和打分的方法能夠快速、有效地解決了作文評分的效率問題,可靠性和準(zhǔn)確性不亞于人工評分的水平,完全可以作為人工評分的補(bǔ)充手段。由此看來,智能評分系統(tǒng)的發(fā)展值得期盼。
一、IntelliMetric系統(tǒng)概述
IntelliMetric系統(tǒng)發(fā)布于1998年1月,是第一個提供給教育機(jī)構(gòu)的智能作文評分軟件,相比傳統(tǒng)的人工評閱具有許多優(yōu)點(diǎn),如:準(zhǔn)確 度大于個人評分,尤其大于單人人工評分;提供即時反饋等等。發(fā)布以后,系統(tǒng)得到了廣泛的應(yīng)用。
IntelliMetric系統(tǒng)作為一個智能評分系統(tǒng),充分模擬了人工評分的過程。系統(tǒng)開發(fā)時經(jīng)過了大量的測試培訓(xùn),即不斷通過人工糾正其自動認(rèn)定的給分點(diǎn),直至契合。值得提出的是,系統(tǒng)不是將所有的給分點(diǎn)簡單地相加,而是通過分析給分點(diǎn)之間的聚合關(guān)系,模擬人工從整體上看待作文并給出判斷,這一點(diǎn)上跟人工評分的過程是一致的。
對于每一個給分點(diǎn)刺激和提示,IntelliMetric系統(tǒng)創(chuàng)建了一個獨(dú)特的解決方案,主要的給分點(diǎn)、次要的給分點(diǎn)、聚群給分點(diǎn)和分散給分點(diǎn),都有不同的分?jǐn)?shù)賦值。每一個刺激或提示,這相當(dāng)于人工閱卷時我們先將作文的得分點(diǎn)做上標(biāo)記,然后回過頭來審視通篇看所有的這些給分點(diǎn)是否形成整體,主題是否突出,連貫是否流暢。正因為如此,IntelliMetric系統(tǒng)能夠?qū)崿F(xiàn)令人滿意的`高匹配的評閱結(jié)果。
二、IntelliMetric系統(tǒng)評分依據(jù)
IntelliMetric系統(tǒng)的評分依據(jù)主要根據(jù)其對作文進(jìn)行的300多個變量的分析,這些變量包括語義學(xué)、造句法等與主題有關(guān)的一切因素,其數(shù)量和認(rèn)定的準(zhǔn)確度還在發(fā)展當(dāng)中。概括起來,IntelliMetric系統(tǒng)評分依據(jù)從宏觀到微觀具有幾個方面功能特征:
首先是聚焦度(Focus)和整體性(Unity),系統(tǒng)高度關(guān)注指向?qū)懽髂康牡木劢苟群鸵恢滦裕瑢o分點(diǎn)的聚合關(guān)系賦值有統(tǒng)籌考慮,同時,也不排斥出現(xiàn)的單個觀點(diǎn)的出現(xiàn),注意到意義的關(guān)聯(lián)度,做到點(diǎn)和面的全盤考慮。
其次是深化(Development)和拓展(Elaboration),系統(tǒng)關(guān)注文章內(nèi)容的廣度和概念的拓展深度,關(guān)注對主題的深化表述論述過程,注意意義點(diǎn)之間的線性關(guān)聯(lián),做到點(diǎn)與點(diǎn)的流程考慮。
三、IntelliMetric系統(tǒng)局限性及關(guān)于智能評分系統(tǒng)的思考
IntelliMetric系統(tǒng)再好,它還是屬于工具,少不了它的局限性。 首先,系統(tǒng)測試時大大依賴于標(biāo)準(zhǔn)的人工評閱專家。系統(tǒng)需要明確的給分點(diǎn)提示和整體把握流程,而這樣的專家往往也是仁者見仁智者見智的,很難取得統(tǒng)一。輸入不夠?qū)е螺敵鼍窒,使用系統(tǒng)進(jìn)行機(jī)評時我們會發(fā)現(xiàn)系統(tǒng)遺漏了給分點(diǎn)或整體把握不靈的情況。
從目前各種智能評分系統(tǒng)的使用看來,各種系統(tǒng)的設(shè)計都利用了多種現(xiàn)代信息處理技術(shù), 主要包括自然語言微觀和宏觀處理技術(shù)、檢索技術(shù)和統(tǒng)計分析技術(shù)等,但由于所使用的各種技術(shù)成熟程度不同,主要由于對自然語言處理微觀宏觀標(biāo)準(zhǔn)的建立和人工智能化程度還遠(yuǎn)遠(yuǎn)不夠,系統(tǒng)的分析能力難免存在較大局限性。目前,由于涉及專利問題,各種智能評分系統(tǒng)所采用的自然語言處理微宏技術(shù)都還沒有公開,這是一個遺憾,對我們進(jìn)一步開展研究很不利。
智能評分系統(tǒng)在對評分模型進(jìn)行訓(xùn)練并建立基礎(chǔ)數(shù)據(jù)庫、形成建模,是提高其工作質(zhì)量,即作文評分的信度的關(guān)鍵。接下來,我們應(yīng)充分借鑒語言測試領(lǐng)域的成果,充分發(fā)展自然語言處理微宏技術(shù),在語言表述、思想內(nèi)容和結(jié)構(gòu)等方面進(jìn)行聯(lián)動賦值,并植入智能系統(tǒng)。還要在程序上進(jìn)一步模擬人工流程,對自動評分模型進(jìn)行反復(fù)訓(xùn)練調(diào)試,才能提高機(jī)評的信度,為語言教學(xué)提供強(qiáng)有力的輔助。

英語作文 篇3
Nowadays, a lot of recreational activities are available for people to release their stress of work or study. Recreational activities have aroused a hot debate in society. When it comes to recreational activities, people’s ideas are not cut from the same cloth.
Abundant recreational activities make people’s life more colorful and people can release their stress with amusement. Also, participating in recreational activities helps promote our competence. However, too much recreational activities will bring problems. For instance, many young students are addicted to online games, which will generate bad effects on their studies and might lead bad consequences.
In my opinion, we should keep a balance between amusement and study or work. Of course, we should join some recreational activities after study, but we need arrange our time properly. Only in this way can recreational activities provide more benefits for us.
